- the creation of synthetic receptors and self-assembly. For synthetic ease, the receptors and assemblies routinely possess a high degree of symmetry, which lends them an aspect of aesthetic beauty. Pictures of electron orbitals similarly can be seen as akin to works of art. This similarity was an early
- draw for me to the fields of supramolecular chemistry and molecular orbital theory, because I grew up in a household filled with art. In addition to art, my childhood was filled with repairing and constructing mechanical entities, such as internal combustion motors, where many components work together
- to achieve a function. Analogously, the field of supramolecular chemistry creates systems of high complexity that achieve functions or perform tasks. Therefore, in retrospect a career in supramolecular chemistry appears to be simply an extension of childhood hobbies involving art and auto-mechanics

- Florida. I went on to study at Williams College in Massachusetts. I knew chemistry was going to be my major subject, but my interests were broad, leading me to think that a liberal arts education might be a good fit.

Is organic chemistry science – and does this question make any sense at all?
Beilstein J. Org. Chem. 2015, 11, 893–896, doi:10.3762/bjoc.11.100
- principles should be counted as proper sciences. Mechanics, for example, was a proper science. Chemistry, in contrast, for Kant was improperly called science, that is, he considered it to be not a science at all but rather a “systematic art” [4]. Note, though, that the qualification of chemistry as a
- systematic art was not meant as a disqualifier: Systematic arts for Kant were experimental doctrines, that is, the empirical investigation of natural phenomena guided by reason “where we begin by the observable large-scale properties of matter and then attempt to determine its internal structure “from the
